Check javax.lang.model.type.TypeMirror is a primitive type

Is there any way I can check that a javax.lang.model.type.TypeMirror is a primitive type? I've tried instanceof PrimitiveType but this always yields true since PrimitiveType extends TypeMirror.

Thank you for the help.

Solution

  • Per https://docs.oracle.com/javase/7/docs/api/javax/lang/model/type/TypeMirror.html

    To implement operations based on the class of an TypeMirror object, either use a visitor or use the result of the getKind() method. Using instanceof is not necessarily a reliable idiom for determining the effective class of an object in this modeling hierarchy since an implementation may choose to have a single object implement multiple TypeMirror subinterfaces.

    Try calling getKind() rather than instanceOf.
